Hey Greg,
Thank you for your service.
Regarding your choices, we actually own an 11 Edge Sport (mine) and an 11 Explorer (hers). We have two small children, and although the Edge can hold two strollers two kids, and most of their stuff, we just needed a little extra room. I brought my wife to look at the EX, we placed our double stroller behind the third row seat and closed the hatch. Everything fit. When you have the inlaws with you or friends and you need that extra seating plus the room for the kids and their stuff the Ex is the way to go. We are totally happy with it.
With that said, I love my Edge. It's sporty, comfortable, and it's sharp looking. When the weathers crummy and I can't drive my sports car, I'm just as pleased driving the Edge. You can't go wrong with the comfort and features of the Edge. A co worker just got the new Journey and as nice as it is I like my interior and exterior far better. I think Ford chose better materials for the interior. They have nice textures, pleasing colors, and a very good fit and finish. You just don't get that feeling in the Dodge. It feels....cold, hard, plasticy. If you like the hard edges of Dodges design language then go for it, for me I really like the smooth front end of the Edge better. Do your research and read as much as you can on all three.
Just so you could see them side by side, here are pictures of my wife's Ex and my Edge. If you want anymore or of something specific drop a line.
